What is a good filament extruder?

[modesdo]

Hi,

I'm thinking about getting a filament extruder in order to make my own filament. I've seen a couple of them:

The ExtrusionBot: advantage comes with its own spooling device
The Filastruder: it comes as a kit and is less expensive
The Filabot Wee: also a kit, and it seems very slow compared to the advertising literature of the others.

Does anybody have any experience with any of these or another option I haven't mentioned?

I'm tending towards the ExtrusionBot because it is fully assembled with a spooler.

Thanks much!

There's a UK based company that make an extruder called the Noztek Pro, it's a ready made unit and looks quite good www.noztek.com
